“They’d been at Sunday school, and sometimes they go to the store to get candy,’’ the grandmother said. “They were headed back to the church for regular service . . . when the sign fell [on the little girl] and slashed her face. The bricks fell on top of my grandson.

“The little girl was hysterical. She had an asthma attack. My grandson was just sitting there dazed.”

The kids were pulled from the rubble with cuts and bruises and taken to Kings County Hospital. A good Samaritan passer-by helped pull out the boy, his grandma said.

Both kids were released from the hospital later Sunday.

“It was a miracle” they weren’t hurt worse, Margaret Jackson said. “We could have been preparing for funerals. But God blesses us. He saved them.’’

A city Department of Buildings spokeswoman said a violation was issued to the structure’s owner for failure to maintain the property properly.

DOB officials also issued emergency orders to have a sidewalk shed erected at the scene for the safety of passers-by.
